INSECT nnsrnovnn.

Application filed January This invention relates to an insect destroying apparatus, the general object of the in vention being to provide a machine for pro ducing vapors or gases, means for spraying the vapors or gases upon the plants and means for covering the plants while they are being sprayed.

Another object of the invention is to provide means for feeding the material to form the gas into a furnace where the material is burned to produce the gas and means for forcing the gas from the furnace into the spraying device.

A further object of the invention is to actuate the before mentioned means from one of the ground wheels of the device.

Figure 1 is an elevation of the complete device.

Figure 2 is a rear view of the vapor producing device with the trailer omitted.

Figure 3 is a section on line 3-3 of Fig ure 2.

' Figure 4 is an end view of the trailer.

Figure 5 is a section on line 55 of Figure 4.

In these views, A indicates a truck having means thereon for producing vapors and gas and B indicates a trailer adapted to be attached to the truck and having means thereon for spraying the vapors upon the plants.

The truck comprises a frame 1 which includes the adjustable yoke 2 which carries the spindles for the wheels 3. One of these wheels is provided with the lugs 4 so that I it will have proper traction under all conditions of the soil. A set of links 5 connects a cross piece 6 of the frame with each spindle carrying part of the yoke and the single trees 7 are connected to the vertical links of these sets. The tongue of the truck is shown at 8. A cylinder-like furnace 9 is horizontally arranged on the frame under a hopper 10, the material from the hopper passing through the tube 11 into the furnace when the agitator 12 is being actuated. A fan 13 is also carried by the truck and the outlet tube 14 of this fan is in communication with the furnace. The front part of the furnace is provided with a door 15 so that access can be had to the same and a perforated partition 16 is placed in the rear part of the furnace. A ring gear 17 is carried by the Wheel 3 which is provided with the lugs anda pinion 18 meshes with this gear, said pinion be ing carried by a shaft 19 journaled in the frame and being connected with the shaft 20 30, 1925. Serial No. 5,867.

of the agitator through shown generally at 21. This shaft 20 is connected by the belt and pulleys 22 with the shaft 23 of the fan. Thus both the agitator and the fan will be driven from one of the ground wheels of the truck.

The trailer B is fastened to the frame of the truck by the connections 24 and this trailer comprises the bars 25 supported by the wheels 26 and the braced frame 27 which connects the bars 25 together and which also acts to support a canopyor cover 28 formed of canvas or the like. The trailer carries the pipes 29, some of which are formed to straddle rows of plants and these pipes are provided with the nozzles 30 and the deflectors 31. A pipe 32 connects the pipes on the trailer with the outlet 33 of the furnace.

From the foregoing it will be seen that when the apparatus is pulled across a field of plants and material, such as sulphur placed in the hopper 10, this material being fed into the furnace will be burned therein and thus produce a vapor or gas which is blown by the fan through the pipes on the trailer and will escape from tlie belt and pulleys these pipes through the nozzles and will:

be directed upon the plants by the deflectors. The gases will be held surrounding the plants for a while by the canopy or cover 27 so that all insects upon the plants and around the same will be killed. Any suitable material, such as charcoal, can be placed in the furnace to start combustion of the sulphur or other material. As shown the device will treat two rows of plants at the same time but it will of course be understood that the device-can be made of any desired size. The cover is made with an open front and with a slack rear end so that the gases will be retained therein for the maximum amountof time without the cover damaging the plant.

The device can be used for treating cotton plants for boll weevil and the like and it also can be used for treating other plants.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is I apparatus at the class described eomranged Within the frame for straddling rows of plants, a plurality of nozzles carried by the pipes, deflectors supported above the 10 nozzles and a removable flexible cover for said frame.

In testimony whereof I affix my signature.
